About Nesta

Nesta is an innovation foundation. For us, innovation means turning bold ideas into reality and changing lives for the better. We use our expertise, skills and funding in areas where there are big challenges facing society.

The UK’s current energy retail model has been around for 30 years and is based on the supplier hub model, where suppliers act as the single link between customers and the wholesale energy market.

We debated and discussed five alternative models that we think could accelerate household decarbonisation, and could form the basis of a future retail market.

On Tuesday 30 April 9:30-11:00, we hosted a hybrid event to delve into findings from our new report on the future of energy retail, exploring how the electricity retail market could be designed to better support the delivery of net zero.
